MAX FRANKEL, OF GREENPORT, NEW YORK.

PERIVIUTATION-LOCK.

SPECIFICATION forming part of Letters Patent No. 351,026, dated October 19, 1886.

Application led March 13, 1886. Serial No. 195,066.

To all whom it may concern.-

Be it known that I, MAX FRANKEL, a citizen ofthe UnitedStates, and aresident of Greenport, in the county of Suffolk and State ot' New York, haveinvented certain new and useful Iinproveinentsin Pernlutation-Locks, of which the following is a specification.

The object of my invention is to provide a permutation-lock of simple and inexpensive construction, which is especially adapted for use upon cash boxes, drawers: deed boxes, safes, 85o.; and it consists, essentially, in the peculiar construction of the tumbler-s, vibrating bolt, and (logging device acting in combination with them, whereby the retraction of the bolt by force is prevented until the tuinblers are set, and when the tuinblers are Set and the bolt thrown in the unlocked position it tends to keep the turnblers set.

In the accompanying drawings, forming part of this specitication, in which like parts are indicated by similar reference -letters wherever they occur, Figure l is a vertical section taken through line x m of the lockcase, Fig. 2, which ligure is a transverse section taken through line y y of Fig. l.

I have shown my invention as applied to a small safedoor, which is represented by A, the jarnb of the door being represented by B. To the inside of the door is secured the case C, which may be an open box of any light metal housing secured to the inside ofthe door. One end of the box is slotted, and through this opening the bolt D protrudes to engage the inner edge of thejamb B when in the locked position, as seen in full line, Fig. 1. rl`his bolt D, as shown in the drawings, is secured to the spindle E, which is provided at the outer end with the customary crosshead or handle, e. rlhis pivoted bolt has an upwardly projecting arm, d, and a lower hooked arm, d. The ends of tht se arms when the bolt is locked, as in the position shown in full line in Fig. l, are in close proximity to the peripheries of the tnmblers F, of which there may be any desired number-three being shown in the drawings*either the inner or outer one of which is fixed upon the lockarbor, to turn with the dial-knob G, and the other tumblers being loosely journaled upon the arbor, and having engaging-pins g, asis (No model.)

common in permutation-locks. Each of the tumblers is provided with a hooked notch, f, to receive the hooked end d of the bolt D when the notches of the tumblers are inline in front of it. Vhen the hooked arm d enters these notches,the bolt D is in the unlocked position` as seen in dotted line, Fig. l.

It will be seen that so long as the notchesf in the tuniblers are not set up77 or brought in line the arms d d', bearing against the peripheries of the tumblers, prevent the bolt from being thrown from the locked position by force.

While l have shown lthe vibrating bolt secured upon the spindle E, to be thrown in the locked or unlocked position by the handle e, it is obvious that it may be pivoted on a stud inside ot' the door, and the arbor E and its handle omitted, as the bolt would fall by gravity into the notches so soon as the notches in the tumblers are brought in line in front of' its arin or fence d'. By making thearni d with not so much of a vhook as shown the bolt can be thrown in ils locked position by the drivingtuinbler; but I prefer to make the arni d hooked, as shown, to engage in the hooked notches of the tuniblcrs e when the door is unlocked, so that the combination will be fastened when the lock is opened.

The index H, which is secured upon the outside of the door, is ot' the usual construction used with combination or permutation locks, spaced and numbered or lettered in the usual manner. This, with the dial and its knob, are so well known that no speritic description of them is necessary.

What I claiin as new, and desire to secure by Letters Patent, is-

The combination, in a permutation-lock, of the tumblers F, having notches f, the pivoted bolt D, provided with the arm d, and hooked arm d', adapted to enter said notches when the saine are brought in line and hold the tumblers in the unlocked position, the said arms d and cl serving to dog the bolt against unlocking, substantially as shown and described.

MAX FRANKEL.
